Can you please tell me the difference between EFI booting a USB and EFI booting a hard drive, as wheen installing a Linux image on the USB using Rufus, it's booting, but when the same image is installed on a hard drive, it's not detected by the UEFI firmware:

  • The USB is just running in live mode, I suspect you are not correctly making the hard disk bootable. Which Linux are you installing?

I am assuming you are having uefi firmware and you are trying to boot from USB.

First of all you need to use GPT partition, for your USB to get detected in the uefi boot priority option.

The next thing that you should be careful about is, your Linux iso image. It has to be compatible with efi, otherwise Rufus will not format the USB. What I mean by compatible is, you need to have efi firmware(*.efi) for your platform in the efi/boot/ directory in you Linux iso image. You can check that by mounting Linux iso.
